How Does Driclor Work? Driclor contains the active ingredient aluminium chloride that forms a gel matrix in the affected sweat glands. This blocks the sweat glands, which gradually prevents perspiration so any excess sweat is absorbed by the body & disposed of the normal way. In just one to two weeks of regular treatment with Driclor, excessive perspiration should disappear & sufferers should feel cool & dry. How To Use Driclor Roll On Adults & children: Apply Driclor each night & rinse off in the morning. Continue this until sweating decreases during the day. Thereafter, once or twice weekly. Driclor should be applied to dry, clean skin. Avoid using on skin that has recently been shaven, broken, or irritated in any way.
